Default Re: Aluminum Brazing

I always keep some of these rods on hand in my garage and at the shop, they do take practice and if you can monitor the temperature as well as keep the temp as close to 700F as possible and keep the parts clamped together the stuff works great. I've successfully used it with propane and mapp gas but still do a practice run with scrap metal right before doing anything important and watch the temperature by using an infrared point and shoot thermometer so I can get a real good idea how long to keep the heat on the part, then there's a narrow window of time when everything will flow real nice but that window can be much wider if working with larger thicker pieces. The other secret is to constantly clean the metal with a stainless wire brush as the aluminum contaminates really quickly when heated.
